Calcite seed-assisted microbial induced carbonate precipitation (MICP)
Zehner, Jennifer Simone; Røyne, Anja; Sikorski, Pawel (Peer reviewed; Journal article, 2021)Microbial-induced calcium carbonate precipitation (MICP) is a biological process inducing biomineralization of CaCO3. This can be used to form a solid, concrete-like material. To be able to use MICP successfully to produce ... -
Centre for Digital Life Norway - Annual report 2017
Johansen, Finn-Eirik; Brautaset, Trygve; Aune, Marie Hjelmseth; Patriksson, Alexandra; Falkenberg, Liv Eggset; Kleppe, Rune; Dick, Gunnar; Strand, Berit Løkensgard; Eijsink, Vincent; Røyne, Anja; Goksøyr, Anders; Svendsen, John Sigurd Mjøen; Fyhn, Marianne; Vik, Jon Olav; Wentzel, Alexander; Aksnes, Astrid; Bruheim, Per; Carlsen, Sven Magnus; Åm, Heidrun (Research report, 2018) -
Micro-scale studies of microbialinduced carbonate precipitation for the application of biocementation
Zehner, Jennifer (Doctoral theses at NTNU;2021:59, Doctoral thesis, 2021)Cement, which is used as a binding material in conventional concrete, is the second most consumed material by humans, after water. The production process of cement, however, causes a high emission of CO2 and contributes ... -
Microbial-induced calcium carbonate precipitation: An experimental toolbox for in situ and real-time investigation of micro-scale pH evolution
Zehner, Jennifer Simone; Røyne, Anja; Wentzel, Alexander; Sikorski, Pawel (Peer reviewed; Journal article, 2020)Concrete is the second most consumed product by humans, after water. However, the production of conventional concrete causes more than 5% of anthropogenic CO2 emissions and therefore there is a need for emission-reduced ... -
A sample cell for the study of enzyme-induced carbonate precipitation at the grain-scale and its implications for biocementation
Zehner, Jennifer Simone; Røyne, Anja; Sikorski, Pawel (Journal article; Peer reviewed, 2021)Biocementation is commonly based on microbial-induced carbonate precipitation (MICP) or enzyme-induced carbonate precipitation (EICP), where biomineralization of CaCO3 in a granular medium is used to produce a sustainable, ... -
Towards a low CO2 emission building material employing bacterial metabolism (1/2): The bacterial system and prototype production
Røyne, Anja; Phua, Yi Jing; Le, Simone Balzer; Eikjeland, Ina Grosås; Josefsen, Kjell Domaas; Markussen, Sidsel; Myhr, Anders; Throne-Holst, Harald; Sikorski, Pawel; Wentzel, Alexander (Journal article; Peer reviewed, 2019)The production of concrete for construction purposes is a major source of anthropogenic CO2 emissions. One promising avenue towards a more sustainable construction industry is to make use of naturally occurring mineral-microbe ...
